Messaging StandardsBecause messaging is such a fundamental feature for many application architectures, poor choices can have disastrous consequences—affecting performance, scalability, availability, and, ultimately, user acceptance and the financials. In this brief art... more
TransactionsThis article discusses how the analysis of the transaction properties of atomicity, consistency, isolation, and durability (ACID) are crucial to integration design.
Architects and the User ExperienceThe user experience should be thought of as a process that starts as early as when the project is conceived, and continues past deployment into revision and maintenance.
Architecting a Knowledge-Management SystemOne key factor for the success of a knowledge-management system is to plan it around a critical real-world issue. It will also be successful if its future users can frame for themselves the goals and objectives of the system.

Device Management and ProvisioningThe term "provisioning" for a device means to evolve a device to a state in which it can be handed-off to an end user, or end-user team, for their specific use in a functional manner. The device could be a desktop, laptop, server, or mobile device.
ContractsThis article covers what architects should know about contracts and why. Its objective is to enable an architect to identify the clauses in a contract that could affect the design and implementation of a system, and, conversely, how system design mig... more

Tutorial 21: Implementing Optimistic ConcurrencyFor a Web application that allows multiple users to edit data, there is the risk that two users might be editing the same data at the same time. In this tutorial, we'll implement optimistic-concurrency control to handle this risk.
Solution ArchitectureSolution architecture starts with an understanding of the problem, and this is where so many projects fail. Too many people have the idea that solving a problem is all about coding. The coding is the easy part.
The IT EnvironmentLike good actors, architects play many roles�from archaeologist to inventor to mediator to security agent to leader�but often it seems as if technologist were the least of them.
The Software Architect and Organizational ReadinessTo be successful, an architect must be able to assess an organization's readiness to change. Implementing organizational-readiness activities in your project plan is above and beyond the technical process of software architecture. The good thing is t... more
Design Skills: The Practice of DesignTo meet the challenges placed on us by both the customer and our IT leadership, we must understand the whole system of interconnected elements that participate in, affect, and influence the design process. Design is about understanding "the whole sys... more
Perspectives on ASP.NET AJAXMicrosoft ASP.NET AJAX (formerly referred to as "Atlas") adds many new capabilities to ASP.NET 2.0, all of which are geared towards making it easy to add AJAX-based functionality to your Web sites. In this column, we examine ASP.NET AJAX, looking clo... more
Build a Queued WCF Response ServiceWindows Communication Foundation (WCF) enables disconnected work between clients and services. The client posts messages to a queue and the service processes them later. Such interaction permits a different programming model from the default request/... more
Client-Side Web Service Calls with AJAX ExtensionsThere were certainly places where ASP.NET would generate client-side JavaScript, most notably in the validation controls and more recently with the Web Part infrastructure, but it was rarely more than a simple translation of server-side properties in... more
The Client Side of ASP.NET PagesIn this column I'll analyze the client-side source code that ASP.NET pages generate. I'll cover hidden fields such as the well-known view state, but also little known ones such as control state, event validation, event target, and argument and system... more
Security in Windows Communication FoundationWindows Communication Foundation performs a lot of the heavy lifting to make it easier for your service to provide the basic security features that most distributed systems need. The big three protections— confidentiality, integrity, and authenticati... more
Tutorial 1: Creating a Data Access LayerThis is the first tutorial in a lengthy series that will explore techniques for implementing these common patterns in ASP.NET 2.0. We'll start with creating a software architecture composed of a Data Access Layer (DAL) using Typed DataSets, a Busines... more
Tutorial 4: Displaying Data With the ObjectDataSourceAssigning a data Web control's DataSource property to the data to display and then calling the control's DataBind() method is the pattern used in .NET applications. The ObjectDataSource serves as a bridge between the control and any other object.
MSDN Webcast: Microsoft Office Open XML FormatsPreviously, binary formats meant that Office documents were treated like a "black box," but now the open XML formats allow documents to serve as a first-class source of data as they travel through workflow and other business processes and solutions.... more
Step-by-Step Guide to InfoCardIn my April 2006 column I began a discussion of InfoCard, the upcoming identity metasystem, which is being prepared for release in the Windows Vista™ timeframe. If you haven’t read that column, you should definitely start there because I’m going to a... more
A First Look at InfoCardI am going to talk about InfoCard purely in the domain of Web services, because that's the only place you can use the prerelease bits as I write this column (see MS Federated Identity and Access Resource Kit for Sept 2005 CTP). But in the future it w... more
Cutting Edge: Windows Workflow Foundation IIIn last month's column, I presented a helpdesk workflow sample that focused on Windows® Forms client applications. This month I'll discuss ASP.NET workflow applications and the ability to expose a workflow as a Web service and invoke a Web service fr... more
